Alexa has always looked up to her older sister Carrie. Carrie lives in Alexa’s family home, and adores her one-year-old niece Florence. Alexa doesn’t know how they would cope without her. So when Carrie is suspended from her job as a senior nurse, accused of the most terrible crime, Alexa reels in disbelief. Alexa knows how caring Carrie is, and as she watches Florence gurgling and cooing whenever Carrie is around, she knows her little girl is in safe hands.
Alexa’s husband doesn’t trust Carrie. He wants her out of the house, unable to ignore what people are saying about her. But when he suggests that Carrie could be a danger to their daughter, Alexa shuts him out. Nobody will ever come between her and her sister.
Then Florence is hurt while in Carrie’s care and Alexa at last starts to wonder. Alexa has always wanted to protect Carrie from the past they have hidden. But does Alexa know what Carrie wants? And will the secret that has kept the sisters together now destroy her little girl?
